Merge tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform conversion patches from Olof Johansson: "Here are more patches in the progression towards multiplatform, sparse irq conversions in particular. Tegra has a handful of cleanups and general groundwork, but is not quite there yet on full enablement. Platforms that are enabled through this branch are VT8500 and Zynq. Note that i.MX was converted in one of the earlier cleanup branches as well (before we started a separate topic for multiplatform). And both new platforms for this merge window, sunxi and bcm, were merged with multiplatform support enabled." Fix up conflicts mostly as per Olof. * tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) ARM: zynq: Remove all unused mach headers ARM: zynq: add support for ARCH_MULTIPLATFORM ARM: zynq: make use of debug_ll_io_init() ARM: zynq: remove TTC early mapping ARM: tegra: move debug-macro.S to include/debug ARM: tegra: don't include iomap.h from debug-macro.S ARM: tegra: decouple uncompress.h and debug-macro.S ARM: tegra: simplify DEBUG_LL UART selection options ARM: tegra: select SPARSE_IRQ ARM: tegra: enhance timer.c to get IO address from device tree ARM: tegra: enhance timer.c to get IRQ info from device tree ARM: timer: fix checkpatch warnings ARM: tegra: add TWD to device tree ARM: tegra: define DT bindings for and instantiate RTC ARM: tegra: define DT bindings for and instantiate timer clocksource/mtu-nomadik: use apb_pclk clk: ux500: Register mtu apb_pclocks ARM: plat-nomadik: convert platforms to SPARSE_IRQ mfd/db8500-prcmu: use the irq_domain_add_simple() mfd/ab8500-core: use irq_domain_add_simple() ...
